Supermarket adding machine



Feb. 22, 1966 s. M. LIBRANDE SUPERMARKET ADDING MACHINE 2 Sheets-Sheet 2 Filed May 15, 1964 INVENTOR. 514M054 M lawn/as Irrazmsys United States Patent 3,236,446 SUPERMARKET ADDING MACHINE Samuel M. Librande, 1443 1st St. SE., Minot, N. Dak. Filed May 15, 1964, Ser. No. 367,677 3 Claims. (Cl. 235-74) The present invention has relation to adding machines and more particularly to a small adding machine which can be mounted onto a supermarket cart and utilized by a homemaker to total up the cost of groceries placed in her cart. 7

Many small adding machines have been previously advanced. All of these, however, are gear driven and do not function with precision. Further, most of them are quite small and, while they are easy to carry, they are not easily operated.

The device of the present invention presents an adding machine which will mount onto the top rear portions of an ordinary supermarket cart and which has dial-type actuators so that the housewife purchasing groceries can add the amount of each purchase and determine what the total bill will be before reaching the checkout counter.

In addition, the adding machine includes space for putting advertising material on the face of the machine. This helps the grocer to bring specials and bargains in the store to the attention of the housewife.

Separate dials for indicating tens of dollars, dollars, tens of cents and cents are used. When the dials for the 'lower columns are rotated one revolution, the dial for the next higher column is moved one numeral. The information that the lower dial has totaled one revolution (ten numbers) is transferred to the next higher dial with a latch and cam type actuator. When the dial for cents has been moved ten notches, it actuates the dimes or tens dial one notch or number; when the tens dial has been moved ten notches the dollars or hundreds dial is moved one notch or number. The same is true for the tens of dollars dial, which is actuated one number after the dollars dial has moved ten notches or numbers.

The actuating mechanism is easily made, and can be made on a mass product basis at low cost. Nevertheless, precise movement is obtained, and therefore, accurate adding is always insured.

It is an object of the present invention to present a hand-operating adding machine for supermarket carts which has a latch and cam type actutaing mechanism.

In the drawings,

FIG. 6 is a sectional view taken as on line 6-6 in FIG. 4.

Referring to the drawings and the numerals of reference thereon, an adding machine illustrated generally at 10 includes an outer case assembly 11. The outer case assembly 11 has a back member 12 and. a front or top member 13. The upper edge panel 14 of the back member 12 is irregular, as shown. The back member is used to mount the mechanism for the computer and, as will be more fully explained later, the recording discs for the numbers of the adding machine are overlapped slightly so that they are offset from each other.

The front panel 13 is provided with resilient transparent flaps 15 and 16 which are attached to the front panels.

3,236,446 Patented Feb. 22, 1966 The transparent flaps 15 and 16 can be removed or lifted so that newspaper ads or printed material can be placed underneath the flaps and can immediately be seen by a person using the adding machine.

Also, suitable brackets (not shown) are provided for mounting the adding machine onto the upper rear portion of a supermarket cart so that when the cart is being pushed by a person down the isle of a market, the adding machine will extend across substantially the entire width of the cart and the front panel 13 will be in full view of the person pushing the cart.

On the front of the adding machine there are three actuator dials illustrated generally at 20. The actuator dials correspond in construction and usage to a telephone dial. The first dial assembly illustrated generally at 21 is used for registering the cents of each of the purchase. The second dial assembly illustrated generally at 22 is used for recording the tens of cents or dimes of each of the purchases, and the third dial assembly 23 is used for recording the dollars of the purchases or the hundreds unit.

The total amount of the purchases is seen through windows 24 provided at the top edge of the front panel 13 of the adding machine. The windows provide access to view numerals appearing on suitable recording disks which are actuated by the dial mechanisms as will be more fully explained later.

Each of the dials is substantially identical in construction and includes a dial plate 25 having a plurality of finger openings 26 provided therein. A suitable stop 27 is provided for each of the dials adjacent the bottom thereof. The dials are used by placing a finger in the proper aperture and rotating the dial clockwise until the finger strikes the stop.

Numerals indicated generally at 28 are placed on the top surface of the front panel 13 of the adding machine and are arranged as shown in the circular fashion so that one numeral appears through each of the finger apertures of the dial plate. There are ten numerals, ranging from 0 to 9 in counter clockwise direction in each group.

By dialing, in a well known manner, the appropriate numbers indicating the amount of the purchase, this amount will be added to any previous purchases and the total amount will be seen in the windows 24 at the top of the adding machine. The dollar amount of the purchase is recorded by moving the dollars dial assembly 23; the tens of cents amount of the purchase is recorded by moving the dimes dial assembly 22 and the cents amount is recorded by moving the cents dial assembly 21.

The front and back portions 12 and 13, of the adding machine, are joined together with suitable fasteners and form a housing in which the mechanism for operating the adding machine is mounted.

The back portion 12 has (as shown) a number of integrally molded studs or shafts thereon. The mechanism for operating the unit is mounted on these studs.

A plurality of studs 30 (four in number) are integrally molded with the back wall 31 of the back portion 12 and extend toward the front portion. The studs 30 form upright columns on which separate cam actuator assemblies 32 (also four in number) are rotatably mounted. Each of the cam actuator assemblies 32 includes a main hub 33 which has a longitudinally extending receptacle 34 that fits over its associated stud 30. The hubs have radially extending flanges 35 adjacent the lower portions thereof. As can be seen, the flanges 35 are raised upwardly from the lower end of the hubs. The flange 35 on each of the cam actuator assemblies has ten depending pegs or lugs 36 integral with the bottom surface thereof and extending downwardly therefrom, the pegs are positioned adjacent the outer periphery of the flanges 35. There are ten lugs 36 on each of the flanges 35 and they are evenly spaced (36 apart) as are the finger openings on the dial plates.

A separate cam track 40 is integral with an upper surface of each of the flanges 35 and extends around the hub 33. As can perhaps best be seen in FIGS. and 6, the cam track on each of the flanges 35 of the cam actuator assemblies is identical. The track includes a low portion 41 at one side thereof and opposite the low portion there is an actuator notch 42 provided in the cam track. The actuator notch 42 is partially defined by a substantially radial surface 43. Actuator levers, which will be explained later, are actuated by the cam notch.

Above the cam track 40 on the actuators for the cents and dollars column there is a guide 44. The guide 44 is to keep the cam follower positioned on the mechanism. The spacer 44 is not used on the dlme or tens of dollars mechanism as in this mechanism the recording discs which are positioned on the hubs also act as guides.

The hubs 33 each have a shoulder 45. The portions of the hub above shoulders 45 are splined as can be seen in FIGS. 3, 5 and 6. A separate recording disc, generally indicated at 46 is drivably mounted on each of the hubs for the cam actuator assemblies 32 through matching splined hubs. The discs 46 move in parallel planes and move whenever the cam assemblies to which they are attached are rotated. The discs are made so that the discs for the cents and dollars columns are offset from the other discs, The discs are of size so that each has a portion projecting into one of the windows 24. Each of the recording discs is provided with ten numerals 47, which range from zero to nine, and are arranged counterclockwise order, as are the numerals for the fingeroperated dial. The dial plates 25 are also splined to hubs 34 and held with a press fit. The numerals 47 are visible through the window 24.

While each of the recording discs 46 is of the same configuration, it can be seen that there is a cents recording disc 50, a tens or dimes recording disc 51, a dollar or hundreds recording disc 52, and a tens of dollars or thousands recording disc 53. It is to be understood that there are corresponding cam plates for each of the discs. Each dial plate 25 and its recording discs are drivably mounted for rotation with their associated cam actuator as a unit.

If it is desired to have the adding machine record hundreds of dollars as well, an additional set of mechanism would be provided to the left of the existing mecha- In order to add numerals successively, each time the dial to the farthest right, for example the cents dial mechanism 57 (FIG. 5), is rotated one revolution, which means ten cents or units have been recorded, an additional number must be recorded on the recording disc 51 for the dimes or tens window (the next window to the left). Likewise, when the dial for the dimes recording mechanism 54 has been rotated one revolution it must be made to record an additional numeral on the dollars or hundreds recording disc 52. Similarly, when the dial for the dollars recording mechanism 55 has gone one complete revolution or has recorded ten dollars, an additional numeral must be recorded on the recording disc 53 for the tens of dollars. The mechanism for the tens of dollars, illustrated at 56 does not have to actuate any additional mechanism because the limit of this adding machine, as shown, is $99.99. There is no dial plate for the tens of dollars mechanism. The cents mechanism 57 will be the mechanism which is actuated most often.

Therefore, in order to use the adding machine, as shown, there must be three sets of identical transfer mechanism illustrated generally at 58 which will cause the recording disc to the left of the dial mechanism being actuated to record an additional number when the cam actuator has rotated past the ten position for that mechanism. In effect the fact that one dial has rotated, a revolution must be transferred to the next highest column. Stop mechanism is provided for holding the cam actuator, and therefore, the recording dials in their proper position until the dials are mechanically or manually moved during the adding process.

The mechanism for transferring information from the cents to the dimes column is illustrated generally at 60; mechanism for transferring motion from the dimes to the dollar column is illustrated generally at 61; and mechanism for transferring motion from the dollars to the tens of dollars column is illustrated generally at 62. Each of the mechanisms are identical in construction and the parts will be identically numbered.

Each of the transfer mechanisms includes a pivot lever 65 which is rotatably mounted onto a stud 66 that is integral with the back wall 31 of the back case 12. The pivot lever 65 has a suitable support hub which surrounds the stud. The stud extends upright substantially parallel to the studs 30. The pivot levers 65 (three as shown) rest on the inner surface of the wall 31 and are free to move with respect thereto. The upper end of each of the pivot levers 65 has a pin 67 integral therewith and extending outwardly therefrom at substantially right angles to the plane of the lever and parallel to the stud 66. One end of stop guide bracket 68 is rotatably mounted over the pin 67 and extends away from its pivot lever 65 toward the cam mechanism which will be moved when the pivot lever is actuated (toward the left). The stop brackets 68 are offset and the left most portion of each has a longitudinal slot 69 provided therein. The bracket is slidably mounted on a guide pin 70 (the pin fits in slot 69) that in turn is integral with the back wall 31 of the rear portion of the case 12. The stop member 68 is free to slide along the pin 70 but cannot move in direction transverse to the longitudinal axis of the slot. The stop bracket is offset so that the right portion fits over the stop lever 65 and the left portion slides on the rear of the case.

A separate transfer link 73 also is mounted onto the pin 67 of each of the pivot levers 65 and positioned on top of or above the stop member 68 of that pivot lever. The transfer links 73 have slots 74 which fit over the pins 67 on their associated pivot lever.

The transfer links 73 each have two sections. Each has a cam actuator driven section 75 (at the right end of each) and a cam actuator driving section 76 at the left end of each. The transfer links 73 are offset where they mount to the levers 65. Therefore, the driven sections 75 are spaced from the rear wall 31 and are above the flanges of the cam actuator which will drive the particular link (the cam actuator at the right of the link) while the driving sections 76 rest upon the slide along the inner surface of wall 31 and are positioned below the flange of the cam actuator that this link will drive when it is actuated (the cam actuator at the left of the link).

As can be seen in FIG. 5,, a coil spring 77 is attached to a lug 78 on each of the links at a first end thereof and is attached to a lug 79 on the corresponding lever 65 at the second ends thereof. Springs 77 urge the links in direction as indicated by arrow 82. This will cause the driven sections 75 of each of the links (at the right end of the links) to ride upon the cam track 40 of its associated driving cam actuator and the driving section 76 of each of the links (the left ends) will rest upon the pegs 36 which depend from the bottom surface of the flange of the cam actuator which that link will drive. The levers can move transversely within the limits of slots 74.

Each of the driven sections 75 has an outer end or driven hook member 83 integral therewith. The driving sections 76 of each of the transfer links have driving hook members 84 integral therewith. Thus the transfer links are elongated bars having facing hooks at each end thereof.

In order to insure that the cam actuator assemblies, and consequently the recording discs, which are drivably mounted to the actuator assemblies, do not rotate to positions wherein there are no numerals appearing in the windows, a stop mechanism is provided for each cam actuator. The stops make sure the discs will rotate only 36 (one numeral) at a time.

As shown, these stop mechanisms are also identical for each of the actuating assemblies and include a stop lever 87 which is pivotally mounted onto a stud 88 which in turn is integral with the back wall 31 of the back portion 12 of the case. The stop levers 87 are positioned on the lower side of the cam actuator assemblies and have stop edge surfaces 89 which extend to engage the pegs 36 of its associated cam actuator assembly. The levers 87 are urged toward these pegs 36 with a spring 90 which extends from outer end portion 91 of each of the levers to a peg 92 on the next adjacent pivot lever 65 to the right of the lever. For the cam actuator stop lever on the cents mechanism 57 the spring 90 is attached to a peg 93 integral with the back wall 31 of the case. The springs urge the levers toward the pegs 36, and when two of the pegs contact the edge 98 as shown in FIG. 6 the cam actuator is retarded from rotating further because of the resilient action of the springs 90. The springs 90 would have to yield in order to permit the cam actuator assembly to rotate inasmuch as the lever would have to move if the cam rotated.

It can be seen that if the cam actuator assemblies were to be rotated when they are in posit-ion as shown at the left actuator in FIG. 6 the lever 87 would have to rotate in direction as indicated by arrow 94 before the cam actuator could rotate. This resilient stop holds the cam actuators and the recording discs from unwanted rotation but permits rotation under external force. The stops hold the cam actuators and the attached recording discs in ten separate angular positions and at each position there will be a different number appearing in the window 24 for that recording disc. As the discs rotate clockwise the number Will be one higher at each succeeding position up to nine, after which the zero will appear but the recording disc to the left will be actuated to show one additional number.

At the same time the springs 90 urge the pivot levers about their pivotal axis in direction as indicated by arrow 95. This causes the pivot levers to move until the end surface of the stop bracket 68 defining slot 69 strikes pin 70 on which the stop bracket is mounted and prevents further movement of that particular pivot lever. This is the normal position of the pivot lever and the transfer link assemblies. This position is shown in the two left most pivot levers of FIG. 5.

It should be noted that the spring 90 is of a much higher rate than spring 77.

The notch 42 in each of the cam tracks is placed in a predetermined relationship with respect to the numeral zero on its associated recording disc. Therefore, when the numeral 9 on each of the recording discs in its associated window the cam notch 42 of that cam actuator assembly is in position as shown at 100 in FIG. 5. In this position the spring 77 for the transfer link of the mechanism 61 will cause the hook 83 of that transfer link to enter the notch 42. Also, it will be seen at 101 that the hook 84 for that transfer link is against a peg 36 of the cam actuator assembly for the dollars mechanism 55.

It will be immediately seen that if the cam actuator assembly 32 for the dollars mechanism 54 is rotated clockwise (its normal direction for recording a dollars sale with the dial) the last 36 to complete one revolution, the surface 43 of notch 42 will engage a mating surface 102 on the associated hook 83 and cause the transfer link to move in direction as indicated by arrow 104. The hook 84 of the link will pull on the peg 36 at 101 and rotate the cam actuator assembly 32 for the mechanism clockwise one position or 36. This movement of the link will also pivot the associated pivot lever 65 about its axis at the same time and the lever will carry its stop member 68 along with it. The stop member 68 has a downwardly depending foot portion 105 which moves into position to intercept the next rotationally trailing peg 36 (from peg 101) on the cam actuator assembly for mechanism 55 and hold the actuator assembly from rotating more than 36 from inertial forces as the driving transfer link and pivot lever move to the right. The stop position of foot 105 is shown in FIG. 6.

Transfer mechanism driven by the cam actuator assembly 106 shown in FIG. 5 is shown in position when the cam actuator assembly 106 has been moved so that the zero on its driven recording disc is almost fully positioned in its associated window. At this point the hook 83 on the link for the mechanism 60 has almost slipped out of the notch 42. A slight additional rotation of the cam actuator 106 will cause the hook 83 to slip completely out of the notch 42. The hook will not slip out of the notch 42 until the proper number has appeared in the dime window, or in other words, until the cam actuator 107 has rotated one position or notch, or thirtysix degrees.

As soon as the hook 83 is released from the notch 42, the spring 90 will urge the lever .for mechanism 60 in direction as indicated by arrow 110 and the entire transfer link mechanism will move in that direction until the end surface of slot 69 strikes peg and the mechanism 60 will then again be set in its normal position. The next time the notch 42 has been rotated one turn it will again engage and move the mechanism as previously described.

The springs for the stop levers have sufficient force to hold the cam actuators from rotation while the hooks 84 raise up from between the pegs 36 between which they are positioned, as shown in FIG. 6, as the transfer lever 73 is released from the notch 42 and moves to the left to normal osition. The hook 84 has an inclined rear surface 108 to help in this resetting action. The hook 83 will just ride on the cam track 40 for the majority of each revolution of its driving cam. The slots 74 permit the transfer lever to follow the contour of the cams. The low points 41 of the cams are provided to make rotation easier in the middle parts of each revolution of the cam.

In summary when the cents cam actuator 106 is rotated three hundred-sixty degrees (ten numbers), by operating the dial plate 25, the notch 42 will have actuated the transfer link for mechanism 60 and the cam actuator 107 for the dimes or tens column will have been moved thirty-six degrees, or one number. When the cam actuator 107 for the dimes or tens has been rotated three hundred-sixty degrees (ten numbers), either by rotating the cents actuator ten times or by independently moving the dial plate for the dimes column, the mechanism 61 will move the cam actuator 111 thirty-six degrees, thereby registering one additional number in the dollar column. (This means that there have been ten dimes recorded.) When ten dollars have been recorded, and the recording disc 52 for the dollars is rotated one complete revolution of three hundred-sixty degrees, the mechanism 62 will move the tens of dollars actuator 112 thirty-six degrees so that one additional number is recorded on recording disc 53. This will indicate that ten dollars has been added to the list.

Thus the use of the adding machine is simple and the mechanism for transferring the total from one of the actuators to the others is extremely simple. It is comprised merely of a link and hook assembly with suitable stop mechanisms to prevent over-travel of the recording discs.

It should be noted that the stop levers 87 will tend to urge their associated cam actuator to rotate in clockwise direction after the actuator has been moved more than half the way toward its next number. In other words, the action of spring 90 on the lever 87 will put a biasing force on the pegs 36 against which it is being urged. Once the rotationally trailing peg of the pair against which the lever is acting has gone over center on the edge surface 89 of the lever, the force from the spring 90 will act against this peg and tend to rotate the associated actuator in direction as indicated by arrdw 113. The position showing a peg going over center on the stop lever is shown at 114 in FIG. 6. This is the reason the stop foot 105 is necessary, to prevent overtravel of the dials and recording discs from inertia forces caused by the spring bias drive of spring 90.

The slot 74 on each of the transfer links permits movement of the transfer link to allow the hooks 83 and 84 to move in and out of the notches 42 and in and out of engagement with the pegs 36 that they actuate, respectively.

Statring in FIG. 5, from the righthand side, it can be seen that the cam actuator 106 has just moved the transfer link 73 of mechanism 60 toward the right about the pivotal axis of pivot lever 65. This has caused the mechanism 107 to be rotated clockwise thirty-six degrees so that an additional number (one higher) is positioned in the window for that recording disc. The mechanism 106 is rotated by moving the associated dial plate with the finger.

The actuator 107 in turn, is positioned so that it is set to move the transfer link 73 for mechanism 61 when the cam 107 is again rotated clockwise. By rotating the actuator 107 clockwise thirty-six degrees the transfer link 73 of mechanism 61 will move toward the right about the pivotal axis of that pivot lever 65 and the hook 84 in turn will act upon pin 36 (at 101) on the bottomside of the flange 35 for actuator 111 and rotate actuator 111 thirty-six degrees to cause an additional higher number to be produced in the window for that recording disc. Likewise, when the actuator 111 has been rotated sufficiently far in clockwise direction so that its notch 42 engages the hook 83 on the transfer link for mechanism 62, the transfer link for mechanism 62 will move to the right and will drive the cam actuator 112 thirty-six degrees in clockwise direction and record an additional number on that recording disc.

When the hook 83 slips out of its driving notch the springs 90 reset the pivot levers. The hooks 84 slip out from between the pegs 36 and take a bite on the next trailing peg much like a ratchet assembly.

It is to be noted that the pegs 36 are on the bottom side of the flanges 35 and the cam tracks 40 are on the top side of the flanges. The transfer action is from the right cam actuators toward the left cam actuators. For each revolution, or recording of ten numbers, on a cam actuator to the right, the next adjacent cam actuator to the left will be moved thirty-six degrees, or corresponding to one number. As many actuating mechanism as desired can be put in series. The stop feet 105 of the bracket 68 prevent the actuated cam mechanism from rotating more than thirty-six degrees and insure that the number will always be properly positioned in the window and will not rotate past the window, due to inertia or other forces.

In order to insure that the recording discs and cam actuators are assembled properly one of the zelines on the hubs 33 is made larger than the rest. This insures that the discs will always be 'put in place with the numerals in proper relationship to its actuator notch.
